Definitions

  • the present invention relates to a device for fixing any material on a wall, for example, of a vehicle, and concerns more generally fasteners for elements and / or of materials of various natures on a shaped wall any.
  • fasteners such as screws, rivets, ... or the glue. It is also possible to provide fixing lugs welded to the wall.
  • Document DE-U-8913 654 shows a screw screwed into a through-hole tapping made in a wall, the screw being provided with a through-thread, which can be used on either side of the wall to receive a locking means.
  • the object of the present invention is to provide a fixing device for fixing an element of each side of the wall in a single intervention.
  • the invention provides a device for fixing a material on a wall for example of a vehicle, consisting of an assembly element screwed into a thread opening practiced in the thickness of the wall, this element being provided on both sides with a blind thread intended to receive a means of blocking said material.
  • the assembly element is under the general shape of a screw with a head to ensure the direct fixing of the material on the wall.
  • the invention also relates to a use of the fixing device to obtain a shielding of the wall of a vehicle, application which is characterized in that that we fix on the outside a protective plate by screwing in the corresponding thread of the element assembly.
  • a second plate can be fixed on the inside by screwing in the corresponding thread of the connecting element, the first and the second plate being spaced one of the other by a distance corresponding to the thickness of the head of the connecting element.
  • a very first advantage of this invention lies in reducing the number of interventions to be carried out on both sides of the wall to fix a material.
  • Another advantage of the invention lies in the variety of possible combinations in the choice of elements or materials likely to be fixed on the wall.
  • Another advantage of the invention lies in the reduction in the cost of fixing the elements, and within possible development developments which do not require no particular adaptation.
  • FIG 1 there is shown an element assembly 1 screwed into a through thread 2 practiced transversely in a wall 3 and emerging from on either side of it.
  • the wall 3 can be by example the wall of a military vehicle on which we comes to fix, on the outside, a plate 4 and, on the side interior, plates 5 and 6.
  • the assembly element 1 is present in the form of a screw provided with a first blind thread 7 opening at its end 8, and a second blind tapping 9 opening at the level of a head 10 of the assembly element 1.
  • the threads 7 and 9 are axially aligned, but they can be arranged differently.
  • the plate 4 is then fixed on the wall 3 to using a locking means such as a screw 11 screwed into the tapping 7.
  • the plate 5 is fixed to the wall 3 using the assembly element 1, the head 10 comes to bear on said plate 5.
  • the plate 6 is fixed using a fixing means such as a screw 13 screwed into the internal thread 9 of the assembly element 1.
  • plate 4 In the case of a military vehicle that wants to protect, plate 4 is an external overprotection which can be passive or reactive. The nature of this plate 4 is any, homogeneous or combined.
  • the plaques 5 and 6 used alone or in combination are splinter shields whatever the nature of the material component.
  • the connecting element 1 can be made of steel stainless steel or any other steel grade compatible with the material of the wall 3 made of aluminum or titanium.
  • Figure 2 illustrates the attachment of a plate 15 constituting an external protection of the wall 3.
  • the length of the connecting element 1 is slightly less than the thickness of the wall 3 so that, when its head 10 is applied against the inner surface of this wall, the free end is flush with the surface at most external of this wall.
  • the screw 11 fixing plate 15 is fitted with a lock washer 16.
  • Figure 3 illustrates another configuration of fixing of a plate with the assembly element 1 according to the invention.
  • This element 1 is first screwed into the wall 3 for fixing a plate 17, the head 10 being applied to this plate 17. Then, the plate 15 is fixed to using the screw 11, the washer 16 coming against this plate for braking.
  • FIG 4 there is shown a configuration according to which one fixes with the element assembly 1 the plate 17 which is then in intimate contact with the wall 3. Then, the plate 18 is fixed using the screw 13, with a braking washer 19. The plates 17 and 18 are spaced from one another by distance equal to the thickness of the head 10 of the element assembly.
  • the configuration thus obtained can be used when only splinter shields are required, that is to say when the protection offered by the wall 3 is in itself sufficient.
  • the splinter plates 5 and 6 or 17 and 18 are placed at a certain distance one of the other.
  • the invention thus allows the attachment of all kinds of external overprotection by modifying obviously the dimensions of the element assembly 1.
  • This element 1 predisposes the wall 3 of a vehicle to install all kinds of combinations indifferently incorporating external overprotections or not, single or multi-layer splinter guards, equipment both outside and inside.
  • the concept allows development changes (position of equipment) without touch up the structure with the starting mesh.
